Science that explores the mystery of reproduction and its applications to fields

Separated from the veterinary surgery laboratory in 1954 as the veterinary theriogenology laboratory, this laboratory has been engaged in research on artificial insemination of livestock—in particular, research in cellular genetics and morpho-functional research on sperms. We have also greatly contributed to research on the collection, cultivation, preservation and transplantation of embryos as well as the development and spread of transplantation techniques. At present, we are continuing our research on techniques for the in vitro production and preservation of livestock embryos, which have been developed along with embryo transplantation techniques. Our research is focused mainly on studying the causes of fertility decline among dairy cows. In order to apply technologies developed in livestock production to the protection and breeding of various animal species, we are also working to create technologies for the artificial insemination of wild animals.
